Some friends of ours were working on setting up a yard sale and doing some cleaning. They gave us a Brita UltraMax pitcher, but without a filter. They claimed that they couldn't afford the filters. Shortly after receiving the pitcher, I headed over to Walmart to scope out the filters. I found a three-pack for a little under 16 bucks.
After reading over the package, I knew I had enough filters for 6 months! That sounded pretty good to me, so I got them. The one caveat of these is preparation. First, they need to soak in water for about 20 min. Then, the pitcher needs to be filled up, filtered through, and dumped out to get rid of any tiny carbon particles. Once that's done, just take the pitcher out of fridge and refill it when it's empty. One filter lasts two months
I have noticed a huge change in the taste of our water. The chlorine taste is virtually gone and the result is a good bottled water flavor. Also, this filter is supposed to take care of a lot of lead and other bad metals. This could be good if you have old pipes and worry about stuff leaching into your drinking water.
